The i.MX 8DualXLite/8SoloXLite has a different connectivity memory map
than the generic i.MX8 has. One conflicting resource is usb, where the
imx8dxl has a second usb2 phy @5b110000, while the generic imx8 dtsi has
one usb2 phy and one usb3 phy, and the usb3otg @5b110000. When
including both imx8dxl-ss-conn.dtsi and imx8-ss-conn.dtsi as done in
imx8dxl.dtsi this leads to a duplicate unit-address warning.
The usb3otg node was introduced after the initial imx8dxl support with
commit a8bd7f1551 ("arm64: dts: imx8qxp: add cadence usb3 support")
and since then leads to warnings like this (when built with W=2):

For this IP the correct control of the CTS signal for transceiver direction

Therefore we simply use a GPIO now, which is fully under software control

According to the datasheet the phy needs to be held in reset until the
reference clock got stable. Even though no issue was observed, fix this
as the software should always comply with the specification.
Use gpio4 23, which is connected to the phy reset pin. On the same pin
RX_ER was used before, but this signal is optional and can be dropped.
Note: This comes into effect with the phyCOREs SOM hardware revision 4.
In revisions before, this gpio is not connected, and the phy reset is
managed with the global hardware reset circuit.

Merge tag 'locking_urgent_for_v6.17_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking fix from Borislav Petkov:
- Prevent a futex hash leak due to different mm lifetimes
* tag 'locking_urgent_for_v6.17_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
futex: Move futex cleanup to __mmdrop()
Probe and display L3 Cache topology
Add ability to average an added counter
(useful for pre-integrated "counters", such as Watts)
Break the limit of 64 built-in counters.
Assorted bug fixes and minor feature tweaks

/sys/devices/system/cpu/intel_uncore_frequency/package_X_die_Y/
may be readable by all, but
/sys/devices/system/cpu/intel_uncore_frequency/package_X_die_Y/current_freq_khz
may be readable only by root.
Non-root turbostat users see complaints in this scenario.
Fail probe of the interface if we can't read current_freq_khz.

Together with the RAPL MSRs, there are more MSRs gone on DMR, including
PLR (Perf Limit Reasons), and IRTL (Package cstate Interrupt Response
Time Limit) MSRs. The configurable TDP info should also be retrieved
from TPMI based Intel Speed Select Technology feature.
Remove the access of these MSRs for DMR. Improve the DMR platform
feature table to make it more readable at the same time.

External atributes with format "raw" are not printed in summary lines
for nodes/packages (or with option -S). The new format "average"
behaves like "raw" but also adds the summary data

We have out-grown the ability to use a 64-bit memory location
to inventory every possible built-in counter.
Leverage the the CPU_SET(3) macros to break this barrier.
Also, break the Joules & Watts counters into two,
since we can no longer 'or' them together...
